Best Quasar Cannon Build for Helldivers 2

A few days ago Helldivers 2 received a new stratagem, the LAS-99 Quasar Cannon, this powerful cannon instantly jumped to the S-tier weapons by obliterating heavy armor enemies. Check here the best Quasar Cannon build for Terminids and Automatons in Helldivers 2. Meanwhile don’t forget to check our other guides to help you spread Democracy like the Punisher Plasma buid.

This Cannon charges an explosive energy burst capable of killing the strongest enemies with one headshot. The best is that have infinite ammo, you need to wait 8 seconds between each shoot, so make sure you hit the weak points. Given the low rate of fire, you need to use conventional weapons for the regular enemies, or you will be overwhelmed in no time.

Stronger enemies with medium and heavy armor can be destroyed with just one shot if you hit their head, even Chargers and Hulks. Or if you prefer a bigger target, aim for the legs, two shots in the legs are what is needed to take them down. Bile Titans can be a pain but with 2 or 4 headshots from the Quasar Cannon, they will be no more, the same for Tanks and Cannons.

Another great advantage of this cannon is the capacity to destroy bug holes and fabricators with only one shoot, which will save you a lot of grenades.

Quasar Cannon Build for Helldivers 2

Main weapon

The PLAS-1 Scorcher is one of the best weapons to use against bots, can deal with medium armor, and even if you miss the weak spots you still cause good damage thanks to the explosive shoots. For Terminids something like the SMG-37 Defender or the Breaker.

Secondary weapon

P-19 Redeemer, this full-automatic pistol is a good backup to conserve the main ammo, being highly effective against common opponents.

LAS-99 Quasar Cannon

  • Call-in-time: 3 seconds
  • Uses: Unlimited
  • Cooldown time: 480 seconds

The Guard Dog Rover is always one of the best choices to deal with bugs, and when you need to fight robots in the name of Democracy the Shield Generator Pack is the choice.

For the remaining two Stratagems pick however you prefer or that is more adequate to the mission, like an Eagle Airstrike or 500KG Bomb for example.


To deal with bugs, opt for light or medium armor, to try to keep the distance from them. A good passive is the Engineering Kit that reduces recoil when crouching or prone by 30%. Increases initial inventory and holding capacity of grenades by 2.
For fighting the Automatons, Heavy Armor is recommended, a great passive is the Fortified which reduces recoil when crouching or prone by 30% and provides 50% to explosive damage, and believe against bots things get really explosive.
